Did You Know?
Start at 25, not 35
Starting SIP at 25 vs 35 for the same retirement corpus: at 25 you need ₹8,000/month. At 35 you need ₹25,000/month. Ten years delay costs 3× the monthly investment.

How to use this calculator

1

Enter current age and retirement age

The gap between them is your investment horizon.

2

Enter monthly expenses

Current monthly spend. Inflation will adjust this to retirement value.

3

Set inflation rate

India long-run inflation average is 5–6%. Use 6% for conservative planning.

4

Set post-retirement return

The return on your retirement corpus — typically debt/balanced funds at 7–9%.

The formula explained

Two steps: project expenses at retirement using inflation, then find corpus needed to sustain them.

Expenses at Retirement = Current Expenses × (1 + Inflation)^Years
Corpus = Annual Expense × (1 − (1+real return)^−n) ÷ real return

Real return = post-retirement return minus inflation. The SIP needed uses 12% pre-retirement equity return assumption.

Frequently Asked Questions

How much do I need to retire in India?

A common rule: 25× your annual expenses (4% withdrawal rule). For ₹60K/month expenses at retirement = ₹1.8 Cr corpus. But this calculator accounts for inflation and gives a more accurate figure.

What is the 4% rule?

Withdraw 4% of your corpus annually. At this rate, historical data suggests the corpus lasts 30+ years. So ₹1 Cr corpus supports ₹4L/year or ~₹33K/month withdrawal.

Should I include EPF and NPS in this?

Yes. If you expect ₹50L from EPF and ₹30L from NPS at retirement, subtract ₹80L from the required corpus and only target the difference through additional investments.

What if I retire early at 45?

Early retirement dramatically increases the corpus needed — both because expenses grow for more years before retirement and because the corpus must last longer (40+ years instead of 25).

How much do I need to save to retire?

The 25x rule: save 25 times your annual expenses. With a 4% withdrawal rate, your corpus lasts 30+ years. For annual expenses of Rs 6 lakh, you need Rs 1.5 crore. Inflation significantly increases this target over time.
